Lily Allen Threatens Katy Perry

Call it a hunch, but we're pretty sure that "forgive and forget" was not included in Lily Allen's New Year's resolutions.

The outspoken Katy Perry is continuing to pay the price of 2008's "skinnier-version-of-Lily-Allen"-gate, as UK newspaper Sun reports that Allen recently bragged, "I have Katy Perry's number, someone did me a favour [sic]. I'm just waiting for her to open her mouth one more time -- then it hits Facebook." [via Gigwise.com].
